3.5.30

With this release we have cleaned up routes, controllers and zombie code.
We have also added a couple pointers in CONTRIBUTING.md to make it easier to contribute to this package.

In the following days/weeks we aim to further clean up, add more documentation and guides for contributing and improve some UI components.
